Re: Physicists attack cosmological model

But what can be done with so many calculations, dissertations, awards, (incl. Nobels), theories and tenures - all based (and successfully included) in all of these? Not to speak about the 2-3 generations of so brainwashed scientists who imbibed all that with the nursing milk of their Alma Mater.
